Bug#486657: gdm crashes on system shutdown/restart

[Lin Song]

I have the exact same problem as in message #17. The error messages are the same.

I suspect it has something to do with the NVIDIA proprietary drivers (I have 71.84.06 installed right now).

I didn't see this problem before I install the NVIDIA driver (and gcc-4.1, make, build-essential and linux-headers to support the driver).
